Description

  The present invention, for example, when a vehicle such as a taxi vehicle passes a roadside DSRC (Dedicated Short Range Communication) radio device arranged at the entrance of a garage, is mounted on the roadside DSRC radio device and the vehicle. The present invention relates to a vehicle management method in which a DSRC radio communicates with each other to manage the entering / exiting state of the vehicle.

  In recent years, for example, in a taxi company, a DSRC system has been used in order to take in business data composed of rent time and fare for each business from a taxi vehicle and manage it with an office system. In this DSRC system, DSRC radio devices are respectively arranged in a taxi vehicle and in a garage of an office (for example, a garage entry / exit route). As a result, when the taxi vehicle ends on the day of work, that is, when the taxi vehicle passes through the communication area of the DSRC radio at the time of warehousing, the business data of the day is wirelessly transmitted to the office system side, so the business data is stored. There is no need to take a recording medium or the like back to the office, and it is possible to reduce the labor of the driver and increase the management efficiency of the office (see, for example, Patent Document 1).

  In the DSRC system installed in such a taxi company, in order to obtain business data at the time of warehousing, a warehousing route and a merging route are separated and a DSRC radio is arranged on each, A physical distinction is made from the shipping process.

  Further, in the parking fee billing system as well, using the DSRC system as in the above-mentioned Patent Document 1, the garage information transmitted from the garage roadside DSRC radio by providing each of the garage road and the warehousing road in the parking lot. And the delivery information transmitted from the exit roadside DSRC radio are known (for example, Patent Document 2).

JP 2006-92232 A JP 2003-150989 A

  However, in the above-mentioned Patent Documents 1 and 2, when adopting the DSRC system, it is necessary to attach at least two DSRC radio units to the garage or the parking lot in order to manage entry and exit, leading to an increase in cost. Moreover, since it is necessary to provide the entry path and the exit path separately, the efficiency of the space could not be improved.

  The present invention has been made in view of the above-described circumstances, and the object thereof is to control the number of installed DSRC radio units and separately provide a warehousing path and a warehousing path in vehicle warehousing management. It is another object of the present invention to provide a vehicle management method that can suppress the installation cost by suppressing the number of DSRC radio devices arranged and efficiently use the garage space.

  In order to achieve the above-described object, the vehicle management method according to the present invention is characterized by the following (1) and (2).

(1) When a vehicle passes through a roadside DSRC radio connected to a management computing unit having a database, the roadside DSRC radio and the in-vehicle DSRC radio mounted on the vehicle communicate with each other, A vehicle management method for managing an entry / exit state of the vehicle, wherein a vehicle unique ID is transmitted to the roadside DSRC radio via the in-vehicle DSRC radio, and the management computing unit is transmitted through the roadside DSRC radio. The vehicle unique ID is received, the database and the vehicle unique ID are compared and checked to manage the entry / exit state of the vehicle, and the roadside DSRC radio and the in-vehicle DSRC radio When it is determined that the travel distance or required time of the vehicle from the communication to the communication at the time of passing the vehicle is below a preset threshold value, the vehicle unique ID is set to the in-vehicle DSR. No transmission is made to the roadside DSRC radio through the C radio.
(2) When the vehicle passes through the roadside DSRC radio connected to the management computing unit, the roadside DSRC radio and the in-vehicle DSRC radio mounted on the vehicle communicate with each other to enter the vehicle. A vehicle management method for managing an unloading state, wherein data indicating the loading / unloading state of the vehicle is transmitted to the roadside DSRC wireless device via the in-vehicle DSRC wireless device, and the management computing unit is configured to transmit the roadside DSRC wireless device. The data is received through, the entry / exit state indicated by the data is switched to manage the entry / exit state of the vehicle, and the communication between the roadside DSRC radio and the in-vehicle DSRC radio at the time of the previous vehicle passing this time When it is determined that the travel distance or required time of the vehicle until communication when the vehicle passes is less than or equal to a preset threshold value, data indicating the entry / exit state of the vehicle is stored in the in-vehicle DS It does not transmit to the said roadside DSRC radio via an RC radio.

  According to the above (1) and (2), only one roadside DSRC radio device is required to be installed, so that the introduction cost and maintenance labor can be suppressed when the DSRC system is adopted for the vehicle management method. Moreover, since it is not necessary to provide the exit path and the entrance path separately, the garage space can be used effectively. Furthermore, since the vehicle entry / exit state is managed based on the travel distance or required time of the vehicle from the communication at the previous vehicle passage to the communication at the current vehicle passage, for example, the vehicle is stopped near the roadside DSRC radio, traveled back, In the case of reciprocal travel, it is possible to accurately manage the entry / exit state of the taxi vehicle without causing unintended mismanagement of the entry / exit state.

  According to the present invention, in vehicle entry / exit management, the number of installed DSRC radios is reduced to suppress the introduction cost and maintenance effort of the DSRC system, and the garage is not provided with separate entry and exit routes. Space can be used efficiently.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  Hereinafter, a plurality of preferred embodiments according to the present invention will be described in detail with reference to the drawings.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. 1 to 4 show a first embodiment of a vehicle management method according to the present invention, and FIG. 1 is a block diagram showing the overall system configuration of the first embodiment of the vehicle management method according to the present invention. 2 is a side view around the roadside DSRC radio in the vehicle management method of FIG. 1, FIG. 3 is a flowchart for explaining the control operation of the vehicle management method of FIG. 1, and FIG. 4 is a table showing data of warehousing / exit management in the management PC. is there.

  As shown in FIGS. 1 and 2, a vehicle management apparatus 1 using the vehicle management method according to the first embodiment of the present invention includes a DSRC in-vehicle device 3 mounted on a taxi vehicle 2 and a taxi vehicle 2. The operation recording device 4 installed in the office and the office system 8 installed in the office 7 of the taxi company. In addition, a loading / unloading gate (not shown) is provided on the loading / unloading path, and the passage of the taxi vehicle 2 is permitted by opening and closing the blocking bar of the loading / unloading gate according to a command from the vehicle management device 1.

  The DSRC in-vehicle device 3 includes an in-vehicle DSRC radio device 11, a CPU (central processing unit) 12, a memory 13, and an I / F (interface circuit) 14.

The CPU 12 is connected to a speed sensor 15 and a timer 16, which will be described later, in order to acquire various information related to the operation status of the taxi vehicle 2, and outputs from the speed sensor 15 and the timer 16 in addition to control related to the in-vehicle DSRC radio. Processing of the signal to be performed is also performed. The memory 13 is configured by a storage medium device such as a ROM or a RAM, and records and holds the vehicle-mounted device unique ID of the taxi vehicle 2 in addition to the application programs related to the vehicle-mounted DSRC radio 11, the speed sensor 15, and the timer 16. Moreover, it also has a function of temporarily storing business data transmitted from the operation recording device 4.
The memory 13 also includes an EEPROM (Electrically Erasable and Program), and is configured to be able to back up and retain data even when power supply is stopped. The business data is data that is generated by the operation recording device 4 and includes renting time, fare, and the like for each business.

  The speed sensor 15 is attached to a wheel of the taxi vehicle 2, for example, generates a pulse signal according to the rotation speed of the wheel, counts the rotation speed using a pulse counter or the like, and outputs an electrical signal as a rotation speed signal. ing. The timer 16 is a timing element such as a clock timer, and is used to output the time to the CPU 12 at a relatively short predetermined cycle and record the communication time between the in-vehicle DSRC radio 11 and the roadside DSRC radio 6. Is done. The signals output by the speed sensor 15 and the timer 16 are temporarily stored in the memory 13 and are appropriately taken out by the CPU 12 for arithmetic processing. Note that the output signal of the speed sensor 15 is subjected to, for example, integration calculation by the CPU 12 and processed as a travel distance.

  The operation recording device 4 includes an I / F (interface circuit) 17, a CPU (central processing unit) 18, and a memory 19. The CPU 18 mainly performs processing related to collection of business data. The memory 19 records collected business data, and is configured by a storage medium device such as a RAM or a ROM.

  The I / F 14 of the DSRC in-vehicle device 3 and the I / F 17 of the operation recording device 4 are connected to each other via a predetermined electrical cable for communication. Therefore, the CPU 12 of the DSRC in-vehicle device 3 and the CPU 18 of the operation recording device 4 can communicate with each other via the communication electric cable. Accordingly, the business data recorded in the operation storage device 4 is temporarily stored in the memory 19 and then transferred to the DSRC in-vehicle device 3 via the I / F 17 in accordance with a command from the CPU 18 of the operation recording device 4. In the DSRC on-vehicle device 3, the transferred business data is stored in the memory 13 of the DSRC on-vehicle device 3 based on a command from the CPU 12, and transmitted when communicating with the office system 8. Note that serial communication is preferable as communication using the communication electric cable because it is necessary to transmit large-capacity data such as business data.

The office system 8 has one roadside DSRC radio 6 fixedly installed in the entrance / exit of the garage of the office 7 and a management PC that has a database and manages the entry / exit state of taxi vehicles together with business data. (Personal computer) 20. The management PC 20 is, for example, a desktop general-purpose computer, which has operation management software installed therein, and receives, for example, business data for one day transmitted from the vehicle-mounted DSRC vehicle-mounted device 11 through the roadside DSRC radio device 6. Used for taxi crew management.
The roadside DSRC radio device 6 has a control unit for appropriately processing signals transmitted and received.

  The in-vehicle DSRC radio 11 and the roadside DSRC radio 6 are DSRC radios for communicating with each other using, for example, 5.8 GHz radio waves within a very narrow range (for example, about 10 mm). Therefore, the taxi vehicle passes through the vicinity of the roadside DSRC radio device 6 arranged and fixed on the entry / exit road, so that the roadside DSRC radio device 6 and the in-vehicle DSRC radio device 11 can communicate with each other. That is, when the taxi vehicle 2 enters the communication area of the roadside DSRC radio 6 fixedly installed on the entry / exit road, the in-vehicle DSRC radio 11 and the roadside DSRC radio 6 detect each other and communicate with each other. It becomes possible.

  Here, the CPU 12 of the on-board DSRC device calculates and outputs the travel distance from the previous communication based on the output signal of the speed sensor 15 in this communicable state. This travel distance is used to determine the entry / exit state of the taxi vehicle 2 described later.

  Next, the flow of the operation of determining the entering / exiting state of the taxi vehicle 2 in the communicable state will be described in more detail with reference to the flowchart shown in FIG.

  When the taxi vehicle 2 enters the vicinity of the communicable area of the roadside DSRC radio 6 fixedly installed on the entrance / exit road of the office 7, the in-vehicle DSRC radio 11 and the roadside DSRC radio 6 detect each other. (Ie, S101). After detecting each other and the DSRC radios 6 and 11 are in a communicable state, the CPU 12 of the in-vehicle DSRC radio 11 determines whether or not the transmission restriction condition of the in-vehicle unit unique ID is violated (that is, S102). More specifically, the CPU 12 performs the process of S102 by determining whether or not the travel distance is equal to or less than a preset threshold value.

  Here, when the CPU 12 of the in-vehicle DSRC radio device 3 determines that the transmission restriction condition is violated (that is, YES in S102), that is, when the travel distance is equal to or less than the threshold value, the in-vehicle device unique ID is transmitted. The process ends as it is. As a result, entry / exit management of the taxi vehicle 2 is not performed.

  Conversely, if the travel distance is not less than or equal to the threshold, the DSRC on-vehicle device 3 transmits the on-vehicle device unique ID stored in the memory 13 to the management PC 20 via the roadside DSRC radio device 6 (ie, S104).

The management PC 20 compares the vehicle-mounted device ID with the data in the database to determine the presence / absence of data related to the taxi vehicle 2 (ie, S105).
The data in this database is composed of table data indicating the vehicle-mounted device unique ID (vehicle ID) and the entry / exit status information of the vehicle-mounted device unique ID as shown in FIG. Sales data of the customer can also be included.

  If it is determined that there is no data related to the taxi vehicle 2 in the database (i.e., NO in S105), the management PC 20 newly creates data related to the taxi vehicle 2, i.e., data associated with the acquired vehicle-mounted device unique ID ( That is, S106). The fact that the data on the taxi vehicle 2 does not exist in the database is interpreted as the taxi vehicle 2 having entered the garage of the taxi company for the first time, so that the taxi vehicle 2 is included in the newly created data. Record as being in the warehousing state (ie, S107). By performing the warehousing process in this manner (ie, S108), the blockage bar of the warehousing / exiting gate is opened to allow the taxi vehicle 2 to pass (ie, S109).

  Here, it returns to S105 again and continues description. When the management PC 20 determines that the data related to the taxi vehicle 2 is in the database (that is, YES in S105), the entry / exit state recorded in the data in the database is that the taxi vehicle 2 is in the exit state. Or whether it is in the warehousing state (ie, S110). If it is recorded that the data is in the leaving state, the management PC 20 assumes that the taxi vehicle 2 has moved from the leaving state to the entering state, and updates the data by changing to the entering state (ie, S113). . In this way, by performing the warehousing process (ie, S114), the bar for the warehousing / exiting gate is opened and the taxi vehicle 2 is allowed to pass (ie, S109).

  On the other hand, if it is recorded in S105 that the data is in the warehousing state, the management PC 20 assumes that the taxi vehicle 2 has moved from the warehousing state to the evacuating state, and changes the data to be in the leaving state and updates the data. (I.e., S <b> 111), the exit process is performed (i.e., S <b> 112), and the block of the entrance / exit gate is opened to allow the taxi vehicle 2 to pass.

  Here, in the present embodiment, the travel distance is described as the transmission restriction condition, but instead, the CPU 12 of the in-vehicle DSRC radio device 3 determines the time required from the previous communication to the current communication based on the output signal of the timer 16. It is also possible to employ a configuration in which a determination is made based on whether the required time is equal to or less than a preset threshold value.

  Therefore, according to the present embodiment, the vehicle-mounted device unique ID is transmitted to the roadside DSRC wireless device 6 via the vehicle-mounted DSRC wireless device 11, and the management PC 20 receives the vehicle-mounted device unique ID through the roadside DSRC wireless device 11, and the database. Compare the ID with the vehicle-mounted device unique ID and manage the entry / exit status of the taxi vehicle 2, so the number of installed DSRC radios can be reduced in the taxi vehicle entry / exit management, reducing the cost of introducing the DSRC system and the maintenance effort. It is possible to efficiently use the garage space without the need for separate entry and exit routes.

  Further, it is determined that the travel distance or the required time of the taxi vehicle 2 from the communication when the taxi vehicle 2 passes through the communication between the roadside DSRC radio 6 and the vehicle-mounted DSRC radio 11 to the communication when the vehicle passes this time is below a preset threshold value. In such a case, since the vehicle-mounted device unique ID is not transmitted to the roadside DSRC wireless device 6 via the vehicle-mounted DSRC wireless device 11, for example, when stopping, back traveling, or reciprocating traveling is performed near the roadside DSRC wireless device 6. For example, it is possible to accurately manage the entry / exit of the taxi vehicle 2 without erroneous management of the entry / exit state contrary to the intention.

(Second Embodiment)
Next, a modification of the first embodiment described above will be described with reference to FIG. FIG. 5 shows a second embodiment of the vehicle management method according to the present invention, and FIG. 5 is a block configuration diagram showing the overall system configuration of the second embodiment of the vehicle management method according to the present invention. In each of the following embodiments, components that are the same as those in the first embodiment described above, components that are functionally similar, and the like are simplified or omitted by giving the same reference numerals or equivalent symbols in the drawings. To do.

  In the vehicle management apparatus 30 using the vehicle management method of the second embodiment, the speed sensor 35 and the timer 36 are connected to the CPU 18 of the operation recording apparatus 4 as shown in FIG.

  The speed sensor 35 converts the wheel rotation speed of the taxi vehicle 2 into a pulse signal and outputs it as a rotation speed signal to the CPU 18 of the operation recording device 4. The timer 36 outputs time to the CPU 12 at a relatively short predetermined cycle.

  And when the CPU 18 receives a notification from the CPU 12 of the DSRC in-vehicle device 3 that it is in a communicable state with the roadside DSRC radio device 6, based on the output result of the speed sensor 35, the CPU 18 has passed the previous entry / exit route. A travel distance or a predetermined distance until the vehicle passes through the entry / exit route again is calculated. Then, the CPU 18 of the operation recording device 4 immediately transmits the calculation result to the CPU 12 of the DSRC in-vehicle device 3 via the I / Fs 17 and 14.

The CPU 12 of the DSRC OBE 3 temporarily stores the transmitted calculation result in the memory 13, compares this calculation result with a preset threshold value, and violates the transmission restriction condition of the OBE unique ID. Judge whether or not.
Other aspects are the same as in the first embodiment, and have the same effects as the first embodiment.

(Third embodiment)
Next, a third embodiment of the vehicle management method of the present invention will be described with reference to FIGS. FIG. 6 is a table showing a vehicle ID (vehicle equipment unique ID) and warehousing / unloading state data given to the vehicle ID in the vehicle management method of the third embodiment according to the present invention, and FIG. 7 is a vehicle according to the third embodiment. It is a flowchart explaining the control operation of a management method.

  In this embodiment, as shown in FIG. 6, the entry / exit state data is assigned to the vehicle-mounted device unique ID (vehicle ID) recorded and held in the memory 13 of the DSRC vehicle-mounted device 3. In addition, this entry / exit state data is in an exit state by default.

  Next, the flow of the determination operation of the entering / exiting state of the taxi vehicle 2 in this embodiment will be described according to the flowchart shown in FIG.

  When the taxi vehicle 2 enters the vicinity of the communicable area of the roadside DSRC radio 6 fixedly installed on the entrance / exit road of the office 7, the in-vehicle DSRC radio 11 and the roadside DSRC radio 6 detect each other. (That is, S301). After detecting each other and the DSRC radios 6 and 11 are in a communicable state, the CPU 12 of the in-vehicle DSRC radio 3 determines whether or not the entry / exit state data switching restriction (state switching restriction) is violated. (That is, S302). More specifically, as in the first embodiment, the CPU 12 performs the step S302 by determining whether or not the travel distance is equal to or less than a preset threshold value.

  Here, if the CPU 12 of the in-vehicle DSRC radio device 3 determines that it is in conflict with the state switching restriction (that is, YES in S302), that is, if the travel distance is equal to or less than the threshold value, the processing is terminated as it is and the taxi vehicle 2. No entry / exit management is performed. Conversely, if the travel distance is not less than or equal to the threshold value, the DSRC on-vehicle device 3 transmits the entry / exit state data stored in the memory 13 to the roadside DSRC radio device 6 (ie, S303).

  Next, the roadside DSRC radio device 6 determines whether or not the transmitted entry / exit status data indicates a delivery status (ie, S304). The roadside DSRC radio device 6 transmits a warehousing instruction to the management PC 20 (that is, S305) when the warehousing / leaving state data indicates the warehousing state (that is, YES in S304). The management PC 20 performs a warehousing process on the basis of this command, changes the warehousing / leaving state data as warehousing, and transmits the change result to the roadside DSRC radio device 6 (that is, S306, S307).

  Then, the roadside DSRC radio 6 transmits the entry / exit status data to the DSRC on-board device 3 as being in the in-stock status (that is, S309), and receives the entry / exit status data stored in the memory 13 of the DSRC on-board device. Change to state. After this series of processing, the bar for the entry / exit gate is opened (that is, S310), and the taxi vehicle 2 is allowed to pass.

Here, returning to S304, the description will be continued.
The roadside DSRC radio device 6 transmits a command for a warehousing process to the management PC 20 when the warehousing / unloading state data transmitted from the DSRC onboard device 3 indicates a warehousing state (that is, NO in S304) (that is, S311). The management PC 20 performs a delivery process based on this command, performs a process of changing the entry / exit status data as a delivery, and transmits this change result to the roadside DSRC radio device 6 (ie, S312 and S313).

  Then, the roadside DSRC radio 6 transmits the entry / exit state data to the DSRC on-board unit 3 as being in the exit state (ie, S314), and outputs the entry / exit state data stored in the memory 13 of the DSRC on-board unit. Change to state. After this series of processing, the blocking bar of the entry / exit gate is opened (ie, S310).

Also in this embodiment, there exists an effect similar to 1st Embodiment. Further, in the third embodiment, the state switching restriction condition is determined based on the travel distance. However, similarly to the first embodiment, instead of this, it is possible to configure using the time required from the previous communication to the current communication. . Even in this case, the determination is made based on whether the required time is equal to or less than a preset threshold value.
In the present embodiment, for the purpose of reducing the data capacity, for example, it is preferable to associate the warehousing state as “1” and the warehousing state as “0” in the warehousing / leaving state data.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the form, number, arrangement location, and the like of each component in the above-described embodiment are not limited as long as the present invention can be achieved.

  Moreover, although embodiment mentioned above demonstrated and demonstrated the vehicle management method of a taxi vehicle, not only this but the present invention is applicable if it manages the entrance / exit of vehicles, such as a parking lot. Although the management PC has been described as an example of a personal computer, the present invention is not limited to this, and a dedicated arithmetic management device configured with an embedded microcomputer or the like may be used.

FIG. 1 is a block diagram showing the overall system configuration of a first embodiment of a vehicle management method according to the present invention. It is a side view around the roadside DSRC radio in the vehicle management method of FIG. It is a flowchart explaining the control action of the vehicle management method of FIG.
